Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of
u_long.
Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

flag value is already exposed via dv_flags, just not the meaning of the
flags themselves. Use these constants to annotate devices that are
disabled or suspended in devinfo output.
o Added dd_pnpinfo, dd_location, dd_devflags, dd_flags and dd_state
o Copy/initialize these as necessary.
o Document the changes to the interface in devinfo.3.
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
macros, which are only MD because of gratuitous differences between
architectures.
o Change all headers to make use of this. This mainly involves
changing:
#ifdef _BSD_FOO_T_
typedef _BSD_FOO_T_ foo_t;
#undef _BSD_FOO_T_
#endif
to:
#ifndef _FOO_T_DECLARED
typedef __foo_t foo_t;
#define _FOO_T_DECLARED
#endif

The devinfo library provides access to the kernel's internal device
hierarchy and to the I/O resource manager. The library uses a
sysctl(9) interface to obtain a snapshot of the kernel's state which
is then made available to the application.
